Tatsugiri: (竜桐 Paulownia Dragon) - Kuryuu's former nagamaki, is very long with an elaborated, curved blade. Seems to be Kuryuu's default weapon.

Choushimaru: (長子丸 Eldest Son) - A nagamaki, it has a long blade (though shorter than Tatsugiri's), a guard, and a long hilt. Choushimaru is extremely heavy and when it is mastered, a godlike speed and unbeatable destructive force is born that a single katana can't stop. Kuryuu brought this weapon with him when he went to fight Iori Sengoku.

Enhanced Strength: Ango has incredible strength as he is able to wield and swing Choushimaru with ease. He is considered to be the strongest of the officers.

Gaun School Secret Technique: Houkaizan '('崩塊斬Collapsing Mass Slash): Ango holds Choushimaru over his head. He then swings Choushimaru forward using its weight to increase the destructive force of his slash.
